Chapter 11 Firewall Configuration

The default rule for WAN to LAN traffic blocks all incoming connections (WAN to LAN). If 
you wish to allow certain WAN users to have access to your LAN, you will need to create 
custom rules to allow it. 

Alerts are reports on events, such as attacks, that you may want to know about right away. You 
can choose to generate an alert when an attack is detected in the Edit Rule screen (select the 
Send Alert Message to Administrator When Matched check box) or when a rule is matched 
in the Edit Rule screen.

 

When an event generates an alert, a message can be immediately sent 

to an e-mail account that you specify in the Log Settings screen (see the chapter on logs).

Click Firewall and then Default Policy to display the following screen. Activate the firewall 
by selecting the Firewall Enabled check box as seen in the following screen.
